Study of Laparoscopic Radical Hysterectomy Based on Space Anatomy in Patients With IB3 and IIA2 Cervical Cancer

Radical hysterectomy is an effect treatment for FIGO IB3 and IIA2 cervical cancer patients who refuse to receive radical concurrent chemoradiotherapy. However, due to the large tumor size, both patients and surgeons encountered the risk of substantial bleeding, urinary tract damage, and unsatisfactory resection during surgery. Therefore, the exploration of effective and safe surgical treatments is crucial in enhancing the quality of life and prognosis for patients. Laparoscopic radical hysterectomy (LRH) offers the advantages of reduced bleeding and accelerated recovery, thereby minimizing patient discomfort and enhancing their quality of life. However, the prognosis of patients who received LRH or traditional abdominal radical hysterectomy (ARH) remains controversial. We proposed a modified LRH skill based on new space anatomy concept. In our previous single-center study, the result demonstrates that LRH based on space anatomy leads to less intraoperative blood loss and decreased ureteral injury rate compared with traditional skill. The benefits of this new method for patient survival remain uncertain. In this multicenter retrospective study, we aim to assess clinical prognosis and safety of this new LRH compared with traditional abdominal radical hysterectomy (ARH) in FIGO IB3 and IIA2 cervical cancer.
